Zusammenfassung: | An AC-AC matrix converter that converts an input multiphase periodic voltage includes N input voltages that are out of phase into an output multiphase periodic voltage comprising N output voltages that are out of phase, the converter comprising a square matrix array comprising N2 switches. The converter comprises command and control electronics that periodically perform the following two functions: storing N! voltage summations, each voltage summation corresponding to one switch configuration, each switch configuration relating one and only one out-of-phase input voltage and one and only one out-of-phase reference voltage, each voltage summation being the summation of the N differences in absolute value between one and only one out-of-phase input voltage and one and only one out-of-phase reference voltage; switching the matrix array of switches to apply the configuration corresponding to the lowest voltage summation. |
